HA HA BUT TRUE??

Ceilings Landing On, Flies Observations On 

How do flies land on the Ceiling? During WWII Pilot Officer Prune and Flying Officer Prang between Ops undertook an Observational  Research Project to establish how it was achieved. They were unable to agree and came to two different conclusions set out below, who if either was correct?

1.Pilot Officer Prune was of the opinion that the Fly with the throttle set at cruise flew along at the correct height below the ceiling, lowered its under cart,  and performed half loop landing off the top. 

2.Pilot Officer Spin disagreed as unless fitted with an altimeter working inversely from the ceiling down instead of from the ground up the fly would be unlikely to be able to judge the correct radius to avoid nose diving into the ceiling a quarter of the way through the loop.

3.Flying Officer Prang also disagreed as once sufficient airspeed to effect a a good three pointer had been lost the fly would enter an upside down stall, go into an inverted nose dive and have to go around again. As a consequence most flies especially the inexperienced in order to achieve a safe landing would be required to fly a series of vertical circuits of gradually decreasing radius until a successful contact with the ceiling was achieved.

Pilot Officer Noseover also disagreed as landing was in essence a controlled stall onto the ground and it was impossible to stall in an upwards direction. He also added that any landing off the top of a loop would be in the opposite direction to its line of flight adding a significant work load to the already difficult landing procedure. 

Theory 2. By Flying Officer Prang

1.Flying Officer Prang was of the opinion that the fly flew along just below the ceiling, executed a half roll and lowered its under cart as it landed using its brakes (sticky feet) to end the landing run and prevent an inverted stall. 

2.Pilot Officer Prune disagreed as the strain on the under cart would be tremendous and in most cases shear it off causing an inverted crash landing. 

3.Commander Flap also disagreed as after one or two prangs the fly would have no under cart left and would have to be relegated to the fire (fly) dump

DL WWII Mythology

Answer Operational Research has revealed Prune was  actually Right !! for the first time in his life. High speed cameras have shown that flies land off  half loops and absorb some of the landing shock by touching down with their front legs  bringing the other four into position immediately  afterwards.
